Displaying CLOB Column with 4000+ characters

I guess you could display the chunks as seperate rows ?

SELECT ROWNUM as chunk_no,ID, SUBSTR (t1.clob_col, (ROWNUM-1)*4000, 4000) AS chunk
FROM t1
CONNECT BY (ROWNUM-1)*4000 <= LENGTH(t1.clob_col)

or if there is a constraint on the maximum size a clob could be in you system you could hard code the number of text columns returned

SELECT SUBSTR (t1.clob_col, 1, 4000) AS pt1,
       CASE WHEN LENGTH (t1.clob_col) > 4000  THEN SUBSTR (t1.clob_col, 4001, 4000) END AS pt2,
       CASE WHEN LENGTH (t1.clob_col) > 8000  THEN SUBSTR (t1.clob_col, 8001, 4000) END AS pt3,
       CASE WHEN LENGTH (t1.clob_col) > 12000 THEN SUBSTR (t1.clob_col, 1201, 4000) END AS pt4
FROM t1
